Abstract

La présente invention concerne un procédé pour vérifier des descriptions d'appareil pour des appareils de terrain d'automatisation. Selon ce procédé, un automate à états finis est produit à partir d'une description d'appareil qui sert de base à un script de test. Ce script de test est mis en oeuvre afin de vérifier la description d'appareil. Des données sont envoyées à la description d'appareil et sont reçues par celle-ci. Le procédé consiste ensuite à vérifier si les valeurs théoriques établies dans le script de test coïncident avec les valeurs réelles qui sont par exemple fournies par l'appareil de terrain.
